This paper proposes the use of defected ground structure for multiband operation in patch antennas. The technique also leads to reduction of patch size and improvement in bandwidth. Based on this approach a triple band antenna is designed that resonates at three frequencies 1.82, 2.4 and 5.52 GHz. The antenna is modeled and designed using Computer Simulation Technology (CST) Microwave Studio 2014 electromagnetic solver. The simulation results of the antenna show that gain and return loss have almost doubled with previous reported results. The size of the radiating patch is also reduced by about 80.75 %. The antenna has also improved in terms of bandwidth by about 70.5%, 490.5 % and 377.25 % at 1.82, 2.4, 5.52 GHz respectively with earlier reported literature. The designed antenna can be used in communication applications involving IEEE 802.11 a/b/g/n bands and GSM 1.8 GHz band.
